If the system does not detect a situation of wheel  
slipping or poor grip after 300 metres of driving, it  
switches to Hybrid mode.  
brake to immobilise the vehicle interrupts its  
operation.  
The electrical energy is used to  
supplement the petrol engine or recharge the  
traction battery, depending on the type of  
driving.  
This mode will be even more effective if  
the vehicle is fitted with suitable tyres,  
such as winter tyres.  
Operation  
This mode is optimised with specific settings  
which make the most of the dynamic  
performance of this vehicle (power steering,  
accelerator pedal sensitivity, ESC).  
The grip can be improved up to 84 mph (135 km/h)  
using the electric motors; above this speed, the  
vehicle is driven by the front wheels only.  
Comfort  
(Depending on equipment)  
Hill start assist  
Combines Hybrid mode and Comfort mode of DS  
ACTIVE SCAN SUSPENSION.  
This system keeps the vehicle briefly stationary  
(for approximately 2 seconds) when making a hill  
start, while you transfer your foot from the brake  
pedal to the accelerator pedal.  
To favour flexible shock absorption improving  
driving comfort on poor surfaces.  
Facing uphill, with the vehicle stationary, the  
vehicle is held for a short time when the driver  
releases the brake pedal:  
For more information on DS ACTIVE SCAN  
SUSPENSION, refer to the corresponding  
section.  
The system is only active when:  
– If mode D or M is selected on an automatic  
gearbox.  
– The vehicle is completely stationary, with your  
foot on the brake pedal.  
– Certain slope conditions are met.  
– The driver’s door is closed.  
4WD (4-wheel drive)  
(Depending on version)  
Do not leave the vehicle while it is being  
held temporarily by hill start assist.  
Improves the vehicle's grip at low and moderate  
speeds by driving all 4 wheels continuously.  
4WD mode (4-wheel drive) is especially suited  
to driving on snow-covered roads and difficult  
terrain (e.g. mud, sand) as well as ford crossings,  
at moderate speed.  
If someone needs to get out of the vehicle with  
the engine running, apply the parking brake  
manually. Then check that the parking brake  
indicator lamp and the P indicator lamp in the  
electric parking brake control are on fixed.  
Facing downhill, with the vehicle stationary and  
reverse gear engaged, the vehicle is held for a  
short time when the driver releases the brake  
pedal.  
Depending on the driving conditions and the  
battery charge level, 4WD mode may be 100%  
electric.  
The hill start assist function cannot be  
deactivated. However, using the parking

(Depending on engine)  
This system is designed to reduce fuel  
consumption by recommending the most suitable  
gear.  
Stop & Start  
When the function is deactivated, the orange  
indicator lamp is lit; if the engine was in standby,  
it restarts immediately.  
The Stop & Start function puts the engine  
temporarily into standby - STOP mode - during  
phases when the vehicle is stationary (e.g. red  
lights, traffic jams). The engine automatically  
restarts - START mode - as soon as the driver  
indicates the intention of moving off again.  
Primarily designed for urban use, the function  
is intended to reduce fuel consumption and  
exhaust emissions as well as the noise level when  
stationary.  
Operation  
Depending on the driving situation and the  
vehicle's equipment, the system may recommend  
skipping one or more gears.

Gear engagement recommendations are not to be  
considered mandatory. Indeed, the configuration  
of the road, the traffic density and safety remain  
determining factors when choosing the best  
gear. Therefore, the driver remains responsible  
for deciding whether or not to follow the system’s  
advice.  
Opening the bonnet  
Before doing anything under the bonnet,  
deactivate the Stop & Start system to avoid  
any risk of injury caused by the engine
